Definitions
- This invention relates to the field of desmoking and deodorizing assemblies for a gas grill.
- an exhaust opening 1 provided with a burner 2 for desmoking and deodorizing is disposed in back on the top of the combustion chamber 3.
- the parts are identified as follows: A: Gas range, B: Grill, 1: Exhaust opening, 2: Burner for deodorizing.
- a burner 2 is installed in an exhaust opening 1 in the back of the top of a combustion chamber 3, which burns the smoke and odor gases included in the exhaust gas. But it achieves insufficient desmoking and deodorizing effect. Furthermore, the flame nozzle of the desmoking and deodorizing burner may be clogged with boiled mists dropped from a cooking pan since the exhaust opening 1 is installed near the main burner.
- An object of the present invention is an improved desmoking and deodorizing assembly.
- Another object of the present invention is a means for burning smoke and odor gases to be eliminated.
- Another object of the present invention is a means for heating a catalyzer to an optimum temperature to be activated.
- Another object of the present invention is a catalyzer plate located in a place where said catalyzer is not clogged.
- an object of the present invention is the provision of a means for removably disposing a porous catalyzer plate.
- an object of the present invention is the provision of a means for miniaturizing a gas range provided with a desmoking and deodorizing assembly.
- the desmoking and deodorizing is accomplished in the two steps: in the first step, the after burner burns out the exhaust gas including smoke and odor gases to be decomposed into other matter to eliminate smoke and odor, and then, the heat resulting from such burning gases heats the porous catalyzer 41 set in the exhaust opening 40 to the optimum temperature for its activation. In the second step, the heated and activated porous catalyzer 41 absorbes the residual gases going through the exhaust opening 40. In this manner oil and soot which may cause clogging the cells of the catalyzer plate are completely burnt out at the second step, so that stable, durable and effective catalyzing is achieved. This assures that the kitchen will be always maintained in a comfortable condition.
- FIG. 1 is a pictorial view of a gas range equipped with a desmoking and deodorizing assembly
- FIG. 2 is a sectional view of the range of FIG. 1;
- FIG. 3 is a plan view of another gas range:
- FIG. 4 is a sectional view of the range of FIG. 4;
- FIG. 5 is a pictorial view of a gas range equipped with a desmoking and deodorizing assembly of the present invention and;
- FIG. 6 is a sectional view of the range of FIG. 5.
- the invention is embodied in a desmoking and deodorizing assembly to applied to a cooking-use gas range 21 comprising a table top double gas cooking unit, or double stove burners 22, and a grill section 23, disposed under said double burners 22.
- a grill drawer 23 comprises a double sliding mechanism with a drawer 27 with a front panel 28 slidable into a grill chamber 25, on which a water tray 29 is slidable within a certain span restricted by an alternating set of stoppers 30 and 31.
- a grill burner 32 and heat plate 33 are provided thereover.
- a chimney 34 in which smoke and ordor are collected from broiling foods such as fish, meat or the like heated by said grill burner 32 and heat plate 33 and then are guided to an exhaust opening 40 described later.
- the exhaust opening 40 projecting in the back of the gas range 21, communicates with said chimney 34.
- a desmoking and deodorizing porous catalyzer plate 41 is removably disposed in the exhaust opening 40; that is, the porous catalyzer plate 41 with a handle 43 convenient for handling is put on a support rack 42 provided in the exhaust opening 40.
- the mesh of the porous catalyzer 41 is 50-120 cells per square inch.
- An exhaust opening cover 44 having a porous exhaust holes is positioned in and removable from the exhaust opening.
- An after burner disposed in a place adjacent to the outlet 47 of the chimney 34, burns the combustion gas in the chimney 34 to eliminate smoke and odor gases contained therein and the resulting combustion heat contributes to heat said catalyzer to the optimum temperature for activation.
- the location of the after burner may be in any place that satisfies the above heat requirement, either an upward-mount in a proper place in the chimney 34 or a downward-mount in a place adjacent to the outlet 47 of the chimney 34 in as the above embodiment.
- the after burner 46 is so installed that the burner 46 can be easily removed just after the removal of the top plate 24, which is convenient for maintenance.
- FIG. 5 and FIG. 6 Elements are indentified by the following numerals: in FIG. 5 and FIG. 6; 50: ignition knob for the burner, 51: ignition knob for the grill 23, 52: air adjusting knob, 53: handle for grill 23, 48: gas inlet for grill burner 32.
- the exhaust gas including smoke and odor gases burnt by the after burner 46 in the first process goes through the porous catalyzer plate 41 and heats the porous catalyzer plate 41 to the optimum temperature of 300°-400° C. to be activated, which results in completely and effectively absorbing the residual smoke and odor gases
- the catalyzer plate can be smaller in size in comparison with a conventional one. Thus, the overall size of a the gas range provided with the desmoking and deodoring means is minimized.
- porous catalyzer plate 41 is removably set on the rack 42, it is convenient to handle the porous catalyzer plate 41 with the attached handle 43 when it is cleaned or replaced.
- the cell number of the porous catalyzer 50-120 cells per square inch are recommended to get the highest effective desmoking and deodoring. If the cell count is denser than this, the catalyzer may become clogged such that it is difficult to clean, while, if the cell is less dense, catalyzing is less effective
